LAMP-MOUNTING.

Specification of Letters Patent.

Patented Nov. 2'7, 191?.

Application filed June 16, 1917. Serial No. 175,144..

To all whom it may concern:

Be it known that 1, CHARLES E. GODLEY, a citizen of the United States, and residing at Detroit, in the county of Wayne and State of Michigan, have invented a new and Improved Lamp-Mounting, of which the following is, a specification.

This invention relates to dirigible headlights, especially to those that may be mounted on automobiles and power-boats, and its object is to provide a mounting which will hold a lamp of this character firmly in the desired position, which is readily adjustable, and which can be constructed for a moderate price.

This invention consists in the combination with the lamp and the supportfor. the same, of a novel clamping device consisting of a pair of co-acting members, which can be adjusted within wide limits, and a novel universal joint connecting the lamp and the clamping device including a pair of cup-shaped sockets, one in each clamping member, to receive a ball on the end of a stem connected to the lamp. It further consists in the details of construction illustrated in the accompanying drawing and particularly pointed out in the claims.

In the drawing, Figure 1 is a plan of the lamp and of the clamping members. Fig. 2 is an elevation of the clamping members. Fig. 3 is a section on the line 33 of Fig. 2 looking upward. Fig. 4 is a section on the line 14 of Fig. 1.

Similar reference characters refer to like parts throughout the several views.

The clamping device shown in the drawings consists of a main member 1 and a relatively movable member 2. Each one of those members is drilled and tapped to receive a screw 3 provided with a head 4 adapted to engage the support 5 on which the lamp is mounted, which support is often a side bar of a windshield frame. The ends of the threaded portions of these screws may betransversely grooved so that the screws may be readily turned for adjustment.

The two members may be drawn toward each other to cause the support 5 to be engaged by the heads 4: on the screws 3 and by the inclined bearing surfaces 6 on the clamping members by means of screws 7 which are preferably provided with split washers 8 to prevent them from turning back. At

its rear end, the main clamping member 1 is provided with a cup 9 to receive the ball 10 on the stem 11 mounted in the boss 12 on the lamp body 13. This endof the member 1 is also recessed to receive the edge of the cup 15 on the rear end of the clamping member 2, which cup is also formed to receive the ball 10. The ball 10 therefore acts as a fulcrum for the two clamping members 1 and 2 and the tension on the screws 7 determines not only the pressure on this ball but also between the support 5 andthe heads 4 and the bearing faces 6. The rear ends of the clamping members are formed with slots 16 and 17 to permit thestem 11 to swing in a plane at right angles to the support 5.

To engage the clamping members to the support 5, the screws 7 are slacked up and the screws 3 turned until their heads 4 properly engage the support, whereupon the screw 7 is turned down hard. The support will then be rigidly engaged by the heads 4: and inclined seats 6, the friction between the heads and the support preventing the screws 3 from turning. This ressure between the members 1 and 2 is su cient to hold the lamp in any desired position, but not sufiicient to prevent it from being moved.

I claim 1. In adamp mounting, the combination of a pair of clamping members and means to secure them together, adjustable means mounted in each clamping member to secure the clamping device to a support, a lamp, and means connecting the lamp to said clamping device.

2. In a lamp mounting, the combination of a pair of clamping members pivoted upon each other at one end and formed with support-engaging faces at the opposite ends. means to secure the melhbers together, longitudinally adjustable means mounted in each clamping member to secure the clamping device to a support, a lamp, and means connecting the lamp to said clamping device.

3. In a lamp mounting, the combination of a pair of clamping members pivoted upon each other at one end and formed with support-engaging faces at the opposite ends, means to secure the members together, a bolt mounted in each of the members and screw-threaded therein for longitudinal adj ustment and formed with a round head to engage a support, said bolts lying in substantially the same plane which is at right angles to the support, a lamp, and means connecting the lamp to said clamping device.

4 In a lamp mounting, the combination of main and auxiliary clamping members, a bolt to draw them toward each other, longitudinally adjustable bolts mounted in said clamping members and provided with round heads to engage a support positioned between said bolt heads and clamping members, said clamping members formed With spherical sockets at their ends opposite said support, a ball in said sockets, a lamp, and a stem mounted on the lamp and connected to said ball.

5. In a lamp mounting, the combination of a clamping device, a spherical cavity, a ball mounted therein, a lamp, a cylindrical stem connected to said lamp and to said ball, means to force the clamping members together to grip the ball, and adjustable means mounted on each clamping member to secure the same to a support.

6. In a lamp mounting, the combination of a pair of clamping members formed at one end with bearing faces to engage a support and at the other end With spherical seats, a ball in said seats, a, stem extending from said ball and a lamp on the outer end of the stem, a headed bolt adjustably mounted in each of said clamping-members and adapted to force a supporting member against the bearing faces of said clamping members, and means to draw the clamping members toward each other to grip the support and ball.

7. In a lamp mounting, the combination of a clamping device formed of two arts havingspherical cavities in adjacent aces, a ball in said cavities, means to force the clamping members together to grip the ball and a support, a stem connected to the ball, a lamp mounted on the stem, said clamping members being formed With longitudinal slots in the same plane to permit the stem and lamp to swing and adjustable means mounted on each clamping member to secure the same to a, support.
